Method
Build the soup
- Place the chicken breasts into the slow cooker.
- Add the crushed tomatoes, diced tomatoes, chicken broth, onion, garlic, dried basil, dried oregano, red pepper flakes, salt, and black pepper.
Slow cook
- Cook on LOW for 6–7 hours, until the chicken is tender and easily pulls apart, with the lid kept on.
- If using HIGH, cook for 3–4 hours, until the chicken is tender and easily pulls apart.
Shred and finish
- Remove the chicken, shred it with two forks, and return the shredded chicken to the slow cooker.
- Stir in the cooked penne and cook on HIGH for 10 minutes to heat the pasta through.
Serve
- Ladle the soup into bowls.
- Top each bowl with mozzarella, Parmesan, toasted breadcrumbs, and fresh basil for a finished, melted layer.
Notes
For best texture, cook penne separately as written so it doesn’t over-soften in the slow cooker. Refrigerate leftovers in an airtight container up to 3 days; reheat gently on the stovetop or microwave. Freezing is not recommended because pasta can soften further. For a lower-carb swap, replace penne with cooked whole-wheat or legume pasta (still cook separately) and adjust portions to taste.
